正在学孙鑫的“VC++深入理解”，为什么书第二章附码的解决方案可以编译，而我按书...
不编译就显示的错误：严重性 代码 说明 项目 文件 行 禁止显示状态
错误(活动) E1097 未知特性 "no_init_all" WinMain E:\Windows Kits\10\Include\10.0.18362.0\um\winnt.h 3886
编译后增加两条：
1：
严重性 代码 说明 项目 文件 行 禁止显示状态
错误 LNK2001 无法解析的外部符号 main WinMain D:\VS2019工作目录\Windows程序练习\VC++深入理解\Practice\ch02\WinMain_Build\ch02\WinMain\MSVCRT.lib(exe_main.obj) 1
2：
严重性 代码 说明 项目 文件 行 禁止显示状态
错误 LNK1120 1 个无法解析的外部命令 WinMain D:\VS2019工作目录\Windows程序练习\VC++深入理解\Practice\ch02\WinMain_Build\ch02\x64\Release\WinMain.exe 1
这个问题需要你自行研究
首先你没发代码，鬼都不晓得你在讲什么
其次，即使你发出代码，估计也没人会
现在研究mfc的好像不多 源码：

} 把windows sdk 版本 从 10.0.18362.0改为10.0.17763.0后，第一个错误没有了，
但第2,3个错误依然存在，大神能不能提醒一下主要修改哪些属性项？ 你的代码有 main() 函数吗？ #include <windows.h>
